A healthy organization needs people who can question bad leadership. Elon is driving those people away. Those who are left will be those who will support narcissistic leaders in whatever organization they later join.
Obviously there will be exceptions - people on visas etc.
There's no reason to believe this poster has any say over hiring decisions.
I don't know if that is true (written into a contract?), but I also didn't have the heart to tell him that if a company goes bankrupt, they probably don't pay out severance.
I (and I have to believe many) would be thrilled to interview and work with folks who decided to stay at Twitter during the Elon takeover. In an era of wave after wave of frothy VC money anointing so many inexperienced and ineffective leaders in our industry, the opportunity to learn under a uniquely effective, authentic and bold leader are tremendous.
